Vyatta Installation.
1. Download Vyatta template or ISO file for XenCenter.
2. Import the appliance (template) or create VM with ISO. 3. Add both the network interfaces to the VM.
4. Login with username: vyatta and password vyatta.
5. If created through ISO, run “install system” command on the console and install it to the server hard drive. Vyatta Configuration.

II. Creating source type NAT rule .This rule needs to be created for communication of LAN to WAN (i.e. internal to external) and with this rule internal network will have internet access. This is a (and should be a) one way communication, so that only internal can speak to external. Enter “configure” mode.

Managerial Issues
Information related to configuration management and preventative maintenance
When it comes to specific managerial issues related to information systems organizational efficiency plays an important functional role in how managers deal with issues concerning organizational management and organizational growth. Configuration management (CM) is basically a field of management where managers focus on establishing and maintaining consistency of a system or product performance (Princeton, 2014). Church (2010) describes the ever-evolving corporate network architecture as exceedingly complex, and almost 60 percent of the IT issues occur due to configuration problems. Therefore, it is vital that IT-related configuration management create and help maintain an up-to-date record of all the components of the infrastructure. This is a complicated process but having a centralized management database helps with proper maintenance and repair.
“Preventative maintenance is making changes to a system to reduce the chance of future system failure” (Valacich and Schneider, 2012). Preventative maintenance is similar to what most of us do to keep our cars and machines healthy and working to proper specifications. For automobiles, we periodically change our oil, transmission fluid, filters and plugs, and even...

...Electron Configuration Patterns
WE CANNOT KNOW THE EXACT LOCATIONS OF ELECTRONS WITHIN ENERGY LEVELS, BUT WE CAN DESCRIBE PROBABLE REGIONS OF ELECTRON LOCATION.
Our understanding of electron distribution is based on mathematical probabilities that result from knowledge about the behavior of charged particles in an atom:
|a) | |
|b) | |
|c) | |
Consequently, there are three “rules” for predicting the most probable locations of electrons:
1) Electrons always enter the region of lowest energy available.
|This concept is called the |
|Why does it make sense? |
2) Orbitals never hold more than 2 electrons at a time.
|This concept is called the |

...Dynamic Host Configuration Protocol (DHCP)
"The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP)." [1] When a computer uses a static IP address, it means that the computer is manually configured to use a specific IP address. One problem with static assignment, which can result from user error or inattention to detail, occurs when two computers are configured with the same IP address. This creates a conflict that results in loss of service. Using DHCP to dynamically assign IP addresses minimizes these conflicts. Or, just imagine that we have 1000 computers on the network and that we assign the IP address to this computers manually. That will be a lot of work to do. So we need something which can help us to do the job quickly, and this is where the DHCP (Dynamic Host Configuration Protocol) comes in handy. We can configure network settings of all devices (computers, printers...) within network automaticly with the help of DHCP. DHCP stands for Dynamic Host Configuration Protocol. DHCP is all about the request that your computer makes and the response that it receives when assigning a “dynamic” IP address as well as as additional configuration informations. DHCP is a protocol used by networked devices (clients) to obtain various parameters...

...Use of Microsoft SharePoint for Configuration Management in IT Organizations
In the contemporary business marketplace, the requirement for a technology-based system to provide the tools for global organizations to archive and manage information has become an increasingly present issue. The use of a corporate-wide portal, supported by a collaborative, content management platform, provides an Information Management System (IMS) that culminates organizational information and intellectual capital, document storage, and collaborative workspaces into a single resource, accessible through a centralized portal interface (Microsoft, 2006, p. 14).
Configuration Management (CM) encompasses the management of requirements, production, testing, technical documentation, and organizational processes during the lifecycle of a software system’s development. Within Information Technology (IT) organizations, CM defines a series of systematic controls for changes and developments to the software system, which ensure the integrity and traceability of the environment and software configuration throughout the development lifecycle. The CM process is a culmination of activities and support from each level of the organization, ensuring compliance with all applicable standards and guidelines for software development and production.

...Electron Configuration “Lab”
Purpose
The purpose of this lab was to explore how electron configurations vary around the periodic table. The lab also helped us examine the relationships between electron configurations and reactions.
Analysis
The first pattern we discovered was that the sum of the superscripts equaled the number of electrons in the atom. Then, we learned that as you travel across the periodic table (starting from hydrogen up to the element of interest) the superscript increases by one. After finally writing out the electron configurations for all the elements, the results revealed that the location of the element (block s, d, p, or f) states its highest energy sublevel. Using these patterns you can determine the electron configuration of any element by simply by looking at the periodic table. Let’s use Carbon(C) for example. The periodic table tells us that Carbon has a total of six electrons. Its location in the table is in block “p”, specifically the second period which means 2p. Now that you know where the electron configuration ends you simply fill in the preceding sublevels until you reach 2p. Just make sure the superscripts add up to six, the number of electrons in Carbon.
Historically, elements are grouped together because of the similar characteristics that they share. For example, all elements in group 18 are noble gases. Well there can be a connection made by...
